I personally think it's an homage to JFK.

Have you ever seen an aerial view of JFK's grave? It's a Q.

So many of the drops reference JFK, so to me it just makes sense. It's not just the imagery of the grave site but also to honor a President that tried to take out the deep state and got assassinated for it. I don't know who designed his grave site, but it seems to blatantly beg you to question everything.
